如何通过 3 步压缩政府表格照片

1

为您的检查选择正确的目标尺寸

Check your exam notification for the exact photo size limit. Click the matching preset button above (20KB, 50KB, 100KB, or 200KB). For SSC and IBPS, use 50KB. For UPSC, NEET, JEE, use 100KB.

2

上传您的护照尺寸照片

Click Select Photo or drag and drop your JPG file. The photo should have a white or light background, be recent, and clearly show your face. The tool accepts JPG, PNG, and WEBP formats.

3

政府表格照片上传的重要提示

照片规格（常见要求）

大多数印度政府考试门户网站都有这些常见的照片要求。在压缩之前确保您的照片满足所有这些要求：

RequirementStandard Specification
BackgroundWhite or off-white, plain background
Face coverageFace should cover 70–80% of the frame
ExpressionNeutral expression, eyes open and looking at camera
GlassesNot allowed in most recent exam notifications
Photo ageTaken within the last 6 months
FormatJPEG (.jpg) — this tool outputs JPEG automatically
DimensionsTypically 3.5cm × 4.5cm (passport size)
ResolutionAt least 200 DPI for print quality

为什么会出现“文件太大”错误

当您的照片超过允许的最大 KB 时，政府门户网站会显示“文件太大”或“文件大小超出限制”错误。这是最常见的上传错误。只需使用此工具将照片压缩到所需的尺寸并重新上传即可。

为什么会出现“文件太小”错误

一些门户还具有最小文件大小（例如，SSC 要求至少 20KB）。如果您的照片太小，则可能被过度压缩。使用更高的目标大小 — 例如，如果 20KB 出现错误，请尝试 30KB 或 40KB。

签名压缩

大多数政府表格还需要压缩签名图像。过程是相同的 - 在白纸上扫描或拍摄您的签名，然后使用此工具将其压缩到所需的大小。 SSC/IBPS 的典型签名大小限制为 10–20KB，UPSC 的典型签名大小限制为 20–50KB。

常见问题解答

SSC CGL 表格的照片尺寸是多少？
SSC CGL requires a photo between 20KB and 50KB in JPEG format. Use the 50KB preset on this tool to compress your photo to exactly 50KB or below. The photo dimensions should be 3.5cm × 4.5cm with a white background.
UPSC 表格的照片尺寸是多少？
UPSC Civil Services (IAS/IPS) requires a photo between 40KB and 300KB. A 100KB JPEG is the recommended size — it meets the minimum, stays well under the maximum, and maintains excellent quality for identity verification.
IBPS PO/文员表格的照片尺寸是多少？
IBPS PO and Clerk require a photo between 20KB and 50KB in JPEG format, with dimensions of 200×230 pixels. Use the 50KB preset on this tool.
NEET表格的照片尺寸是多少？
NEET UG requires a photo between 10KB and 200KB. A 100KB JPEG is recommended for the best balance of quality and file size. The photo must have a white background and show a clear face.
JEE 主表格的照片尺寸是多少？
JEE Main requires a photo between 10KB and 200KB in JPEG format. Use the 100KB preset for the best quality within the allowed range.
在线压缩我的政府表格照片安全吗？
Yes, completely safe. All compression happens inside your browser using the HTML5 Canvas API — your photo is never uploaded to any server, never stored, and never seen by anyone other than you. This is especially important for sensitive ID photos.
政府表格的照片应采用什么格式？
Almost all Indian government portals require JPEG (.jpg) format. This tool automatically outputs JPEG files, which is the correct format for all government exam and application portals.
我可以使用此工具压缩照片和签名吗？
是的。您可以分别压缩照片和签名。对于签名，将其扫描在白纸上，然后将其上传到此工具并选择适当的大小（对于 SSC/IBPS 通常为 10-20KB，对于 UPSC 通常为 20KB）。
